lMPP OVEMENT IN HAIR-PINS.

Specification forming part of Letters Patent No. 43,439, dated July 5,was.

To all whom it may concern.-

Be it known that I, ANDREW T. THAYER, of the city, county, and State ofNew York, have invented a new and useful Improvement in LadiesHair-Pins; and I do hereby declare that the following is a full, clear,and exact description ther eot, which will enable any person skilled inthe art to make and use the same, referencebeing had to the accompanying drawings, making a part of this specification, in which- Figure 1 is aview of my invention in use or appli ad to the hair; Fig. 2, a detachedand enlarged side view of the same; Fig.3, an edge view of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to .obtain a hairpin which will not slipout of the hair or become casually loosened and detached; and to thisend the invention consists in construct ing the pin with a circularspring at the bend orjunction of the two prongs of the pin, ashereinafter set forth, whereby acertain de gree of elasticity isobtained sut'ticient to cause the two prongs, when pressed in contactand inserted into the hair, to press or bear against the same andbethereby firmly held in position.

'lhe hairpin I construct, as usual, out of a single piece of wire bentor doubled so as to form two prongs, a, a, of equal length, and at thebend I flatten or compress the wire and give at a circular form, so asto constitute a spring, I), as shown clearly in Figs. 1 and 2. Thecompressing or flattening of the Wire at the bend orjunct-ion of theprongs a (a increast s the elasticity of the spring I) and renders thesame more durable than it otherwise would bG-lll fact, a perfect springis obtained, and the prongs a a are bent obliquely outward from the endsthereof, as shown more particularly in Fig. 2, the spring I) having atendency to keep the pron gs a a in that position.

In applying the pin to the hair the prongs a a are pressed together incontact, as'shown in red, Fig. 2, and the spring I), in consequence ofhaving a tendency to force the prongs a m apart, cause the pin to bebound in the hair, so that it cannot become casually loosened ordetached.

Having thus described my invention, I claim as new and desire to secureby Letters Patent, as an improved article of manufacture A hair-pinconstructed or formed with a circular spring, b, at the junction of itsprongs a a, substantially as herein set forth.

ANDREW T. THAYER.
